Evidence Standards
This page explains how exercises get chosen for AnxietyTools, what kind of research they are based on, and where the line is between evidence and speculation.
What kind of evidence gets prioritised
Where possible, exercises on this site are chosen because they line up with findings from systematic reviews, meta-analyses, and randomized controlled trials on stress, anxiety, and breathing or relaxation techniques, along with guidance from reputable public-health sources. A single small study is treated as suggestive, not conclusive. When the underlying research is thin or mixed, that is reflected in the wording used to describe the exercise, rather than glossed over.
Evidence, mechanism, and hypothesis are not the same thing
There is a real difference between evidence (what a study actually measured and found), a plausible mechanism (a reasonable explanation for why something might work, based on physiology), and a hypothesis (an idea that has not been well tested yet). For example, when this site discusses how slow breathing might influence the body's stress response, that is described as a proposed mechanism, not a settled fact. Readers deserve to know which kind of claim they are looking at.
Why the site hedges its language
You will see phrases like 'may help,' 'is thought to,' and 'research suggests' rather than 'will fix' or 'cures.' That is deliberate. Anxiety is influenced by many factors — biology, circumstances, sleep, other health conditions — and no simple exercise works the same way for everyone. Hedged language is not a hedge against liability; it is an attempt to be accurate about what the evidence actually supports.
What this site will not claim
AnxietyTools will not claim that any exercise here cures anxiety, treats a diagnosed condition, or replaces professional treatment. It will not diagnose you, and it will not promise a specific result in a specific amount of time. If a claim can't be backed by a credible source or a well-reasoned mechanism, it should not be on this site — if you spot one, please say so.
How exercises are chosen
Exercises are selected with three questions in mind: is there published research behind this general pattern (a breathing rhythm, a grounding technique, a journaling structure), can it realistically be done in a browser in under a few minutes with no equipment or account, and is it something that seems reasonably safe for most people to try on their own. Anything that requires supervision, specialized equipment, or carries meaningful risk is left out.
How mistakes get corrected
This is a small, independently run site, and mistakes happen — a citation could be misattributed, a study's findings could be summarized imprecisely, or new research could change the picture. If something looks wrong, it gets checked against the source and corrected, with wording adjusted or removed rather than left in place out of convenience.
Who writes this site
AnxietyTools is built and maintained by one person — a marketer, not a doctor, therapist, or psychologist. There is no clinical team and no medical reviewer behind the content. That is exactly why the site leans on published, publicly available research rather than personal authority: the claims are meant to stand on the sources behind them, not on any credential of the person writing them. See the About page for more on who runs this site and why.
Common questions
Is AnxietyTools written or reviewed by doctors or therapists?
No. It is built and maintained by one person without a clinical background. Rather than relying on professional credentials, the site tries to base its exercises on published research and to describe that research honestly, including its limits.
What does 'research suggests' actually mean here?
It means a study, review, or established finding points in that direction for at least some people, not that the outcome is guaranteed. Where evidence is stronger or weaker, the wording tries to reflect that difference rather than flattening everything into a confident claim.
Does the site ever get things wrong?
It can. When an error is found — a misattributed citation or an imprecise summary — it gets corrected against the original source. If you spot something that looks off, feedback is welcome.
Why not just say an exercise works, if it usually does?
Because 'usually' isn't 'always,' and overstating a simple exercise's effect could lead someone to skip professional care they actually need. Careful language is meant to be honest about uncertainty, not to undersell the tools.
